announcement late July
It is a new 12MP sensor with fast readout. So no fancy global shutter
No overheating no recording time limit:
The past hours three Sony A7sII successor testers made it clear the Sony A7sII successor will not have such limitations:
“A7sii successor will not have any recording time limits”
No overheating limitations and no default recording time limit of 29m59secs. So if it comes to professional video use the Sony A7sIII will surely outperform the Canon.
